Specification of Letters Patent.

g Fi "2"?" Patented Nov. 21, 1905.

Application filed March 25,1905. Serial No. 252,089.

To all whom t may concern:

Be it known that we, LnviN FAUs'r and FRANK G. HOGLAND, citizens of theUnited States of America, residing at Rockford, in the county ofl/Vinnebago and State of Illinois, have in vented certain new and usefulImprovements in Locks, of which the following is a specification.

Our invention relates to that class of locks which is commonly known inthe lock trade as mortise-locks. Its principal object is the productionof a strong serviceable lock of the simplest and com pactestconstruction possible.

Our invention has reference more particularly to the escutcheon-cylinderof the lock and the means employed for connecting such cylinder with anddetaching it from its bearings in the lock-case.

Referring to the accompanying drawings, which form a part of thisspecification, Figure 1 is a front view ofa lock embodying our inventionseated in its inclosing mortise, broken away. Fig. 2 is a like view ofthe same with its master-key and escutcheon-cylinder in differentpositions from those shown in Fig. 1. Fig. 3 is an enlarged section atthe dotted line 3 3 in Fig. 1. Fig. 4 is an enlarged section at thedotted line 4 4 in Fig. 2. Fig. 5 is a section at the dotted line 5 5 inFig. 4 of the complete lock and its inclosing mortise. Fig. 6 is asection at the dotted line 6 6 in Fig. L ofthe same. Fig. 7 is a sectionat the dotted line 7 7 inFig. 5 0f parts there shown. Fig. 8 is asection at the dotted line 4 et in Fig. 2 with the escutcheon-cylinderand master-key of the lock detached therefrom. Fig. 9 is a top plan viewof the' escutcheon-cylinder of the lock, showing it operativelysupported in its bearings in the lock-casing and held therein by meansof a retaining-spring. Fig. IO is a sectional detail of suchescutcheon-cylinder, showing the master-key operatively connectedtherewith just as it withdrew it from its bearings vin Fig. 8. Fig. 11is a key for operating the bolt of the lock. Fig. 12 is a section at thedotted line 6 6 in Fig. 4 of the complete lock, showingitsoperating-key, Fig. 1 1, just engaging its locking-bolt.

Like letters of reference indicate corresponding parts thoughout theseveral views.

A is a preferably rectangular box-like structure having anescutcheon-cylinder bearing A extending transversely therethrough, andA2 is a cover having two loops A3 therein and an escutcheon-cylinderbearing A2 extending transversely therethrough opposite to andconcentric with the cylinder-bearing A in the part A and provided with aradial keyhole A5, extending from the perimeter thereof. The parts A A2constitute the case of the lock and are secured together by means ofposts A, which have their ends headed down.

B is an escutcheon-cylinder having a radial keyhole B thereinregistrablewith the keyhole A5 in the lock-case and provided with an annularperipheral groove B2, having the side thereof opposite to and farthestfrom such keyhole A5 cut away, as at B3, and furnished at its outer endwith an annularly-flanged escutcheon B4 and rotatably mounted in thebearings A A4 in the lock-case.

O is a furcated spring fast to the lock-case through the loops A3therein and bestriding the escutcheon-cylinder B and engaging theperipheral annular groove B2 therein, and thereby serving to maintainsuch cylinder against endwise movement in its bearings A A4 in suchlock-case;

D is a master-key of suiiicient width when turned to engage and throweither furcation of the spring O clear out of the groove B2 in its pointwith a hook D for engaging the inner end of such cylinder andwithdrawing it from the lock-case.

E is a bolt having an actuating-slot E in one edge thereof and atransverse detent E2 thereon and is slidably mounted in the lockcase.

F is a tumbler having detent-slots F F2 therein adapted to be engaged bythe detent E2 on the bolt E and pivoted by the end thereof the posts Aof the lock-case and provided with a spring F3, normally maintainingeither of the detent-slots F F2 therein in engagement r with the detentE2 on the bolt E.

the escutcheon-cylinder B and is provided atof farthest from thedetent-slots F F2 to one G is a key provided with a bit Gr' foroperating the bolt E of the lock.

H is a lock-mortise formed in a drawerfront or door-stile H and isprovided with a transverse circular opening H2 to admit theesoutcheon-cylinder B.

After the mortise H and cylinder-opening H2 have been formed in the partH the lock is inserted thereinto until its selvage ct is flush with theface of such mortise, when the escutcheon-cylinder B is inserted throughsuch opening H2 therein into its bearings A A4 in the lock-case,whereupon the furcations of the spring C will engage the peripheralannular groove B2 therein, thereby locking such cylinder securelyagainst endwise movement and at the saine time leaving it perfectly freeto be rotated by the master-key D and operating-key Gr. Whenever it isdesirable or neeessary to remove the lock from its mortise, themaster-key D is inserted into the keyhole B/ in the cylinder B, Fig. 3,and given a quarter-turn to the right, Fig. 4L, when the bit Z thereonwill have contacted and thrown the contiguous furcation of the spring Cclear out of the groove B2 therein and the cut-away portion B3 thereonwill have arrived at a point opposite the other furcation of such springC, thereby leaving the cylinder B free to be withdrawn outward from itsbearings in the lock-case by means of the hook D on the master-key D,Figs. 8 and l0. rlhe employment of the annular flange B14k on theescutcheonof the cylinder B obviously renders it unnecessary toaccurately fit the perimeter of the opening H2 to the periphery of suchcylinder B.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

l. In alock, in combination, alock-case having opposite concentricescutcheon -cylinder bearings and a keyhole therein, anescutcheoncylinder, mounted in such bearings and having a radialkeyhole, registrable with the keyhole in such case, and provided with aperipheral annular groove,Y and a furcated spring fast to the case andbestriding the escutcheoncylinder and engaging' the peripheral annulargroove therein, to maintain such cylinder, against endwisemovement, inits bearings.

2. In alock, in combination, a lock-case having oppositeescutcheon-cylinder bearings and a keyhole therein, anescutcheon-cylinder, rotatably mounted in such bearings and having aradial keyhole, registrable with the keyhole in the lock-case, landprovided with a peripheral annular groove, and furnished, at its outerend, with an annularly-iianged escutcheon, and a furcated spring fast tothe case and bestriding the peripheral annular groove therein,substantially as described.
